How to notate violin scrapes?
According to the "Chop Notation Project" by Casey Dreissen, scrapes are notated according to the attachment below. It's easy enough to make the notehead invisible. It was also easy to find symbols for circular scrapes, but I can't find symbols for inward and outward scrapes. I found some symbols that look similar, but vertical. There is no way to rotate them that I can see. I don't think normal arrows capture the idea either. Any suggestions?
